The idea of the algorithm is to receive a clear passage, it is then converted into a paragraph (usually smaller) cipher in an irreversible manner, and can be simply understood to take a string of input codes (called Pre-maps or information) and convert them to a shorter, fixed number of output sequences that are hashed (also A process called an information digest or information authentication code.

SHA1 Encryption Algorithm
SHA is a data encryption algorithm, which has been developed and improved by encryption experts for many years and has become one of the most secure hashing algorithms, and is widely used. The idea of the algorithm is to receive a clear text and then convert it into a paragraph (usually smaller) cipher in an irreversible way, or simply to take a string of input codes (called Pre-maps or information) and convert them to a shorter, The process of a fixed number of digits

Enabling SSH's powerful chroot capabilities
In previous versions of OpenSSH 4.8P1, to support Chroot, third-party modifications must be used. But since OpenSSH 4.8P1, the chroot functionality has been built-in, and can be set up directly on the server system (CentOS 5.5).
